So I picked up a small orange Florida ricordea from my lfs the other day. Here's a picture of it now: http://imgur.com/27VThyd. When I got it it was a bit bigger and more orange than it is now. Over the past few days I noticed it's been shrinking a little and getting more blue around the edges/center. It also grew a new mouth next to its old one, which leads me to believe it's splitting. Is it normal for a ricordea to shrink and change color when splitting?

Edit: In the three days I've had it, it has also moved off it's original spot in the center of the white plug in the pic. I'm assuming that white crap left on the plug is glue and not ricordea guts?

Good luck with that guy. I can't keep them alive. Not that they die, but that they detach and then disappear. I think my emerald crab has a cave full of them somewhere.

It's pretty normal for them to look smaller (or any coral for that reason) when first introduced into a tank, and it's normal for color to shift a bit when it's getting used to the new surroundings. I wouldn't worry about it. I just hope you don't have a crab who will drag it off to his private treasure hoard of mushrooms.

Try putting it in full shade for a while. They need slow acclimation to new lighting. They will walk a small bit to find a better spot, telling you they aren't happy where they are. When it starts to puff back up. Slowly move it into increasingly higher light.

while i cant speak about the color change your ricordea looks normal to me; Congratulations on the quick split. Ans yes i agree with your assumption that the white residue on the plug is left over glue
